Abstract

The operation device 1 has: a switch array 20 in which operation switches (21, 22, 23, 24) are arranged; electrostatic detection sensors (first electrostatic detection sensor 12, first electrostatic detection sensor 14) which are disposed above or below the switch array 20, thereby detecting two-dimensional coordinate values when an object to be detected, such as a finger of an operator, has comeclose thereto; and a control unit 300 equipped with a determination part for determining whether or not the object to be detected has come close to any one of the operation switches of the switch array 20 on the basis of a detection result of the electrostatic detection sensors.

Description

technical field [0001] The invention relates to operating devices. Background technique [0002] A capacitive switch is proposed, comprising: a transparent electrode disposed on a light-transmitting protective cover covering a control object; and a detection circuit that detects changes in the capacitance of the transparent electrode to ground and outputs a detection signal to drive a control unit. As an operating device (instrument for a vehicle) having such an electrostatic capacitive switch, a device having the following components is known: a display unit for displaying vehicle operation information; a light-transmitting protective cover arranged in front of the display unit to protect the display unit; The capacitive switch includes a transparent electrode arranged at a position corresponding to the display part of the light-transmitting protective cover, and detects a change in the ground capacitance of the transparent electrode and outputs a detection signal; and a co...
